Web service discovery is one important step in Web service composition. As more and more Web services are available, it is necessary to distinguish and rank Web services which have similar functionality. QoS information has substantial impacts on user’s expectation and experience of using a Web service. Therefore QoS is often used as a main factor to distinguish quality of Web services. A number of QoS languages and models have been proposed. And different service providers and participants may use different QoS concepts and measurement methods for describing service quality information. This leads to the issue of QoS semantic interoperability. In this paper, we propose a novel approach for designing and building a QoS ontology for Web services. The ontology can support not only describing QoS information in great detail but also facilitating various service participants expressing their QoS offers and demands at different levels of expectation.
